VALVE-REPAIR TOOL.

Specification of Letters Patent.

Patented May 2, 1922.

Original application filed February 20, 1918, Serial No. 218,301. Divided and this application filed March 11, 1920. SerialNo. 364,994.

T 0 all to ham it may concern Be it known that I, HENRY PHILLIP KRAFT, a citizen of the United States of America, residing in Ridgewood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Valve-Repair Tools, of which the following is a specification.

The invention has to do with a valve repair tool and is in the nature of an improvement upon the construction disclosed in my Patent No. 1,199,084, of September 26, 1916.

The present application is a division of my application, Serial No. 218,301, filed February 20, 1918.

The structure to which my improvement is directed comprises generally an instrument-carrying body portion provided with a die for repairing external threads of a pneumatic tire valve, and an attached instrument-carrying handle portion which may have at one end a tap for repairing the internal threads of such valve and at the other end, a suitable device, such as a screwdriver, for withdrawing the valve parts or insides from the valve casing.

A purpose of the invention is to provide an improved form of screwdriver attachment, whereby the length of the tool can be considerably reduced and the amount of material used and the cost correspondingly lessened without affecting the operating eiiiciency of the instrument. This I accomplish by employing an operating portion preferably in the form of an annular ring in spaced relation to the screwdriver, and permitting the valve casing to be received between the operating portion and the screwdriver. This permits the length of the device to be considerably shortened in comparison with a structure where there is no space afforded between the screwdriver and the operating portion, with the resultant necessity of elongating the screwdriver sufliciently to permit itto enter the valve casing and cooperate with the valve parts. To these and other ends the invention consists in certain improvements and details of parts, as will be hereinafter more fully described and pointed out in the following claims.

In the drawings,

Figure l is a side elevation showing a preferred embodiment of the invention;

Fig. 2 is a longitudinal sectional view on line 22 of Fig. 1; and

Fig. 3 is a side elevation.

Like reference characters throughout the several. views indicate similar parts.

In the structure shown A designates the instrument-carrying body portion which may be provided with a die A for dressing the external threads of a valve casing. The body portion A has a longitudinally-extending central opening A and B designates generally an instrument-carrying handle portion or handle member which is rigidly secured in a transverse opening extending through the body portion A. The handle portion B carries at one end a tap B with which the interior threads of a valve casing can be repaired, while B designates a screwdriver at the opposite end for removing or inserting the valve parts.

The screwdriver B is seated upon a shoulder B of the handle portion B. The screwdriver also carries a substantially cylindrical extension B which is turned inwardly around the handle portion B and engages a second shoulder B thus being swiveled on the handle B close to the body portion A. The screwdriver B is provided with an annular manipulating portion or ring B which is preferably formed integral therewith, but spaced from the screw-driver body, affording a recessB between the screwdriver and the manipulating portion, which recess may receive the outer end part of the valve casing' into which the screwdriver is inserted. This arrangement permits the screwdriver to assume the proper operating position with respect to the valve parts to be removed from a valve casing, and with a tool of minimum length, owing to the saving afforded by disposing a part of the valve casing in the space between the screwdriver and the manipulating portion 13. This also requires less material in manufacturing the tool, resulting in a lighter structure and a certain measure of economy in saving of material.

The inventive idea herein set forth may receive other embodiments than that herein specifically illustrated and described.

lVhat is claimed is:

1; A tire valve repair tool comprising a hollow body portion, a handle member eX- tending transversely through the body portion and secured to it, a screwdriver swiveled upon the handle member in close proximity to said body portion, and an annular operating portion connected to and surrounding the screwdriver in spaced relationship, whereby the valve casing can be located between the screwdriver and the operating portion.

2. A tire valve repair tool comprising a rod portion and a screwdriver swiveled upon said rod portion, said screwdriver comprising a projecting screwdriver proper and an annular operating portion connected to and surrounding the screwdriver in spaced rela tionship, whereby the valve casing may be located between the screwdriver proper and the operating portion.

3. A tire valve repair tool, comprising a tool member, and a screwdriver member at one side thereof, said screwdriver member comprising a part projecting from said tool member, and a swiveled part on said projecting part in close proximity to said tool member, said swiveled member having thereon a projecting screwdriver proper and an annular operating portion connected to and surrounding the screwdriver proper in spaced relationship, whereby the valve casing may be located between the screwdriver proper and the operating portion.

In witness whereof, I have hereunto signed my name.

HENRY PHILLIP KRAFT.
